  • 현재, 전세계의 전력산업은 수직통합적 독점산업에서 부문간 경쟁산업으로 변화하고 민영화를 통한 시상경쟁원리가 도입되고 있다. 이러한 전세계적 전력산업 구조개편에 발맞추고, 전력산업에서의 효율을 제고하기 위하여 우리나라도 전력산업에 시장경쟁 체제를 도입하고 발전산업에 민영화론 추진하고 있다. 2001년 4인, 전력을 거래하기 위한 한국전력거래소가 발족되었으며 6개의 발전자회사의 설립을 통하여 발전부문의 경쟁체제가 도입되었으며, 2003년부터 본격적인 도매경쟁 시장이 도입될 전망이다. 이러한 새로운 시장 환경아래에서 전력거래가 원활하게 이루어지고, 시장이 안정화되기 위해서는 정부, 전력거래소, 발전사업자 등과 같은 시장참여자들이 전력시장을 분석할 수 있는 방법론 및 모델을 확보하고 있어야 한다. 따라서, 본 논문에서는 이러한 전력시장을 분석하기 위한 방법론으로 게임이론을 적용하여 각 발전사업자의 보수전략(Maintenance strategy)을 분석하고자 한다. 이론 통해 각 발전사업자는 보수전략을 수립하는데 이용할 수 있고, 시장규제자의 측면에서는 전력시장이 효율적으로 가동되고 있는지 여부를 판단할 수 있는 유력한 도구로도 활용될 수 있을 것으로 예상된다.

  • Background: The purpose of this study was to identify the effects of morphological Change of cervical spine to apply to neck retraction and extension regarding the straight deformity of cervical spine. Methods: A 40-year male subject with straight deformity of cervical spine participated in this study. The study subject underwent a cervical lateral radiography on the static position, neck retraction and neck extension on standing. Measurement method were using computer-based digital radiogram on a picture achieving computer system forthe centroid method, Cobb's angle and Jackson's angle. Results: Neck retraction was increased kyphosis on the C2-4 with lordosis on the C5-7. Neck extension was increased lordosis on the C2-7. Conclusions: These findings suggest that neck retraction was increased kyphosis and neck extension was increased lordosis based on the straight deformity of cervical spine. Therefore, we should be consider that neck extension exercise when increased lordosis for the patients of straight deformity of cervical spine.

  • 편측 왜소증의 얼굴을 상하악과 하악 모두 신장할 필요가 있는 경우 하악을 신장하여 상악도 신장시키는 방법을 최근 소개한 바 있으나 본 논문에서는 오히려 상악을 신장시킬 때 하악도 같이 신장시키는 방법을 개발하여 좋은 결과를 얻었다. 두 명의 편측안면 왜소증 환자에서 양악 동시에 골 신장술을 시행하였다. Ortiz Monasterio의 방법과 달리 상악은 구내 르포트씨 제일 골절단술을 시행하였고, 하악은 구내 시상분할 골 절단술을 이용하여 골신장시 저항을 최소한으로 줄이려 하였다. 편방향 구내 골 신장기와 스플린트를 이용하여 양악 골신장술을 시행하였다. 5일의 잠재기 후 매일 1mm의 골신장을 시행하였고 6주에서 8주간의 경화기를 둔 후, 골 신장기와 스플린트를 제거하였다. 골신장 길이는 각각 13mm와 15mm이었고, 특이할 만한 부작용은 관찰되지 않았다. 이에 본 교실에서는 상악신장을 바탕으로 양악을 신장시키는 새로운 술식을 보고하는 바이다.

  • Objective : The purpose of this study is to examine the clinical effect of Auricular Acupuncture therapy on ankle sprain Methods : This study was carried out on the 48 patients who had been treated at chonan oriental hospital from December 1st, 2003 to April 30th, 2004. 48 patients had a diagnosis of ankle sprain by x-ray or physical test. we treated 48 patients by Auricular Acupuncture therapy. Results and Conclusions 1. We operated Auricular Acupuncture on the foot point(발점), the ankle point(발목점), the heel point(발뒤꿈치점), the zero point(제로점)and the thalamus point(시상점). 2. The efficacy of Auricular Acupuncture therapy was 75% when we set a standard thing more than good(良好) 3. The Auricular Acupuncture therapy is effective of ankle sprain patients, but we thought that it needed to prove effect of Auricular Acupuncture therapy for efficient application by more clinical researches.

  • Objectives: This is a case report about the effect of Korean medicine on blepharoptosis and ocular motility disorders that occur with thalamus, midbrain, and cerebellum infarctions. Methods: The patient was treated using Korean medicine such as acupuncture, moxibustion, and herbal medicine (Boyanghwano-tang-gamibang). The change of blepharoptosis was evaluated by measurement of palpebral fissure width (PFW), marginal reflex distance-1 (MRD1), and marginal reflex distance-2 (MRD2). The change inocular motility disorders was evaluated by comparison using photographs of the extraocular movements of the patient. We used the Numeric Rating Scale-11 (NRS-11) of diplopia and dizziness to evaluate the effectiveness of treatment. Results: After treatment, blepharoptosis and ocular motility disorders were improved. The NRS-11 score of dizziness decreased from 10 to 7, and diplopia disappeared after Korean medicine treatment. Conclusions: According to this study, Korean medicine can be effective for treating blepharoptosis and ocular motility disorders in thalamus, midbrain, and cerebellum infarctions.

  • BSSRO (bilateral sagittal split ramus osteotomy) is frequently performed to correct dentofacial deformity and malocclusion. Among its complications the incidence of post-operative facial nerve palsy is very rare, but it is one of the most serious complications. The case of a 21-year-old male patient who underwent facial nerve palsy after BSSRO is described. After surgical intervention and conservative therapy, the patient recovered his facial nerve function successfully.

  • A fast response analyzer for measuring carbon dioxide concentration has been developed for transient characteristic and researches tested on internal combustion engine. The analyzer uses the well known NDIR(Non-Dispersive Infrared) method with miniaturized detection system, giving a time constant of approximately 30 microsecond, and sampling module consists of capillary tube. Since the transit time and the time constant of the sampling system depend on the sampling conditions, it is necessary to investigate the characteristics of sampling system before applied to exhaust gas measurement in engine. A unique method was designed to study the influence of the diameter of transfer sample line and operating conditions of the FRNDIR on transit time and time constant. A database of transit time and time constant was built up for different measured and simulated pressure conditions. The database can be used for correcting eventual $CO_2$ concentration measurement.

  • This study aimed to investigate the effects of Chaihushugansan and Chaihuyigantang on the change of monoamine-contents in the hypothalamus of mice induced by the immobilization stress. Each formula(1.0g/kg) was injected intragastrically to mice 1 hour prior to the immobilzation stress(15 minutes) before measuring the change of monoamine-contents level in mice hypothalamus. The results were as follows: 1. DA content at control group showed significant change. CHSGS group and CHYGT group showed significant decrease.(P<0.05) 2. NE content of the control group was increased than normal group. NE content of the CHYGT group was shown a significant decrease than control group.(P<0.05) 3. DOPAC contents didn't show significant changes at any groups. 4. 5-HT contents didn't show significant changes at any groups. 5. 5-HIAA contents at CHSGS group and CHYGT group showed signifiant changes.(P<0.05, 0.01) These data revealed that chaihushugansan and chaihuyigantang might have the anti-stress effect through the control of DA and NE contents in the hypothalamus.
